Edit a pre-existing ood_portal.yml configuration file

from ondemandutils.editors import ood_portal

# Open, edit, and save the ood_portal.yml file located at /etc/ood/config/ood_portal.yaml.
with ood_portal.edit("/etc/ood/config/ood_portal.yaml") as config:
    config.servername = "ondemand-testing"
    config.server_aliases = []
    config.ssl = None
    config.public_root = "/var/snap/ondemand/common/var/www/public"
    config.log_root = "/var/snap/ondemand/common/var/logs/ondemand"
    config.pun_stage_cmd = "sudo /snap/ondemand/current/nginx_stage/sbin/nginx_stage"

Add Dex configuration to the ood_portal.yml configuration file

from ondemandutils.editors import ood_portal
from ondemandutils.models import DexConfig

with ood_portal.edit("/etc/ood/config/ood_portal.yaml") as config:
    dex = DexConfig(
        http_port = 5556,
        tls_cert = "/var/snap/ondemand/common/tls.cert",
        tls_key = "/var/snap/ondemand/common/tls.secret",
    )
    config.dex = dex

nginx_stage

This module provides and API for editing nginx_stage.yml configuration files, creating them if they do not exist. Here's some common nginx operations you can perform on the nginx_stage.yml configuration file using this editor:

Edit a pre-existing nginx_stage.yml configuration file

from ondemandutils.editors import nginx_stage

with nginx_stage.edit("/etc/ood/config/nginx_stage.yml") as config:
    config.pun_access_log_path = "/var/snap/ondemand/common/var/log/nginx/%{user}/access.log"
    config.pun_error_log_path = "/var/snap/ondemand/common/var/log/nginx/%{user}/error.log"
    config.passenger_ruby = "/snap/ondemand/common/usr/bin/ruby"
    config.passenger_nodejs = "/snap/ondemand/common/bin/node"
    config.passenger_root = "/snap/ondemand/current/opt/passenger/locations.ini"
